Abstract
We report a simple NMR experiment measuring individual Cu-63-Cu-63 ind irect nuclear coupling frequencies in YBa2Cu3O7. We show that the coup ling interaction at T = 5K is of quite short range, indicating an anit ferromagnetic correlation length xi of similar to 1 lattice constant o r less.
